Atto m eys A CATION FILED JULY @1914- JOHN A. RUTHERFORD, GREAT FALLS, MONTANA EXPLOSION-ENGINE TRACTOR.

application filed July 3, 1914.

To all whom it may concern:

Be it known that I, JUHN A. Ru'rnuaronn, a citizen of the United States, residing at "Great Falls, inthe county of Cascade and State of Montana, have invented a new and useful Explosion-Engine Tractor, of which the following is a specification.

The present invention 'relates to improvements ih xplosion engine tractors, one ohject of the invention, heing the provision of a tractor, in which a plate or hase carries the reversing gear, and the transmitting gear, so that the same may he assemhled and adjusted at one place, and finally connected tothe frame ofthe tractoiyand not necessitate the positioning of the various elements upon the frame of the tractor.

\Vith the-foregoing and other ohjects in view which will appear as the description proceeds, theinvention resides in the cone hination and arrangement of parts-and in the details of ci-mstruction hereinafter de scribed and claimed, it heing understood that cl'iangcs in. the precise emhodiment of the invention herein disclosed can he made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings illustrated a view partly in plan and partly in section of the frame of a tractor having the present invention applied.

Referring to the drawings, the numeral 1 designates the frame of a tractor, which in the present instance is taken indicative of any form of channeior I-heam used forthis pur-' pose. A plate or base 2 is adapted to he connected thereto by anysuitable means indieated at and such hase carries-the forward hearing 3 for the explosionengine (lI1Ve.Sl1tft 4 and the rear hearings 5 for the two ali-ned shafts 6 provided with the All I 'of the shaft 4 beingdisposed therein and in the bearing 3 'exteriorly of the housing 10, there being keyed or fixed upon the shaft ,4 within the housing 10, the low speed gear 11 and the high speed gear 12. A shaft 15 is journaled parallel to the shaft 4 and splined thcreupon'viiithin the housing 1Q are the two gears 13 and-14, which are provided with means (not-shown) for operating the- Specification of Letters Patent.

'and il for cooperation with the respm Serial No. 845,537.

same so that the gear .s't may he placed in mesh with the gear 1'3 i0 increase the sptied at which the present tractor is driven or by means of which the giars ll and l3 are placed in mesh for the ower speed.

A housing it; is disposed to the rear of the housilrc l0 and is carrie I by the plate 2, this housing ll; forming lln housing for the reversing mechanism of t 10 present structure. The shaft 15 extends through. the housing 16 and has its rear end joulnaled in the hearing 17 carried hy the plate while freely rotatable upon thJ shaft [5 within the housing 16 are the two level pinions 1S and 19, the said hovel pin'ions heine provided with their lOHpQVtliYL. clutch members '20 ive clutch niemhers 22 and/23 of' the splined Inemher 24-. This memlier is operated man-u-. ally through an mechanism desirable (not shown).

of the housing 16, is ashaft 28 which has keyed upon its inner ind,.the large hovel pinion 2:"), which is in nesh at all times with the hevel pinions lHaml 1!),the small pinion 30 being fixed tothe sh ft 28 so that a forward or reverse inovei ient' may he trans-- n'ntted from the pinion. 3t) tothe g al- 31 of.

thcgears that constitut: the varial ilcspeed mechanism in the housing 10, the reversingmechanism included in, the housing-16 and the differential transmission, may he properly assemhled upon'tl 0 base 2 and after such assemhlagre, the same may he moved so as to he placed upon the frame of the,trac

assemhle and finally ins 2a] 1.

What is claimed 1s A transmission and; for tractors, includ ing a flat base plate, separate end and.

intermediate. housings detach'al'ilfy secured shafts journaled within the intermediate housing and one of the end housings, parallel transverse shafts the first one ofwhich upon the base plate, rarallel longitudinal named end housing, a differential connected to the alining shafts, means for transmitting motion from the differential to the first transverse shaft, a. ear carried by said first transverse shaft an within the intermediate housing, opposed gears within said intermediate housing and upon one of the shafts, said gears being loosely mounted, and meshing with the gear on the transverse shaft, means for coupling either of said opposed gears to its longitudinal shaft, gears shiftable. along 'said longitudinal shaft and within the other end housing, spaced gears upon the other longitudinal shaft and within said end housing, said gears and the shiftahle gears constituting change speed gearing.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JOHN A. RUTHERFORD.
